The Electronic Structure of Mixed Self-Assembled Monolayers
The electronic structure of mixed self-assembled monolayers (SAMs) on Au(111) surfaces is modeled using slab-type density-functional theory calculations. The studied molecules have a dipolar character induced by polar and electron donating or accepting tail-group substituents. The resulting electronic structure of mixed layers is found to differ qualitatively from a simple superposition of thos...
متن کاملElectronic transport in self-assembled alkanethiol monolayers
Electron tunneling through self-assembled monolayers of alkanethiols is investigated. Temperature-dependent current– voltage measurements are performed to distinguish between di erent conduction mechanisms. Temperature-independent electron transport is observed, proving direct tunneling as the dominant conduction mechanism of alkanethiols. An exponential dependence of tunneling current on molec...
متن کاملFormation and Structure of Self-Assembled Monolayers.
The field of self-assembled monolayers (SAMs) has witnessed tremendous growth in synthetic sophistication and depth of characterization over the past 15 years.1 However, it is interesting to comment on the modest beginning and on important milestones. The field really began much earlier than is now recognized. In 1946 Zisman published the preparation of a monomolecular layer by adsorption (self...
متن کاملModification of electronic properties of graphene with self-assembled monolayers.
Integration of organic and inorganic electronic materials is one of the emerging approaches to achieve novel material functionalities. Here, we demonstrate a stable self-assembled monolayer of an alkylsilane grown at the surface of graphite and graphene. Detailed characterization of the system using scanning probe microscopy, X-ray photoelectron spectroscopy, and transport measurements reveals ...
متن کاملMicrocontact Printing of Proteins on Mixed Self-Assembled Monolayers
Microcontact printing of proteins from an elastomeric stamp has been demonstrated on a limited number of substrates. This work explores the generality of this method of patterning proteins by examining the role of surface wettability of both the substrate and the stamp in microcontact printing. The substrates used in this study consisted of two-component, mixed self-assembled monolayers (SAMs) ...
